Emotional permanence

So bf & I have been together for over a year now, in the first 9ish months we were practically inseparable. I do believe it was almost co-dependent so we decided to cut it down. So for the past 6 months we’ve been spending less time together. For a bit now I’ve felt like I’ve struggled with emotional permanence. So whenever we’re together I’m secure I know I love him etc. but after a while I start to not feel the love if I’m not around him. Does this mean I’ve lost feelings for him?
